Hi guys,
I am here in hopes that maybe you all can give me a hand with my computer issues. I have recently begun using an internet filtering service called "X3 Pro" in an attempt to filter the content coming through on my family computer. I have noticed though that once this program was installed on my computer it began bumping my computer up to 100% usage after the install restart. I have uninstalled the program and then re-installed it thinking this may fix the issue, and I am still facing the same issue. I currently run Windows XP (32 bit) home edition. I keep the computer updated with the latest Windows updates and also run microsoft security essentials for my anti-virus. My firewall is currently disabled as I was thinking that this was also possibly causing the problem. I run a high speed, cable internet connection and loading websites on Google Chrome and Internet Explorer is extremely slow. (Twitter has taken as much as 5 minutes to load up before).

If any of you may have any suggestions as to help me fix this issue I would greatly appreciate it. Thanks!

I was unable to locate an Internet filtering service known as "X3 Pro". But I did find one called X3Watch PRO. Is that the one you are using? If so they have a support page and 877 number.


If thats the service you're using and paying $7.00 a month for it. It's time for them to do their job and support your service.

When Task Manager shows 100% load, it is not necessarily true. TM can't count CPU load correctly when an application uses a non-standard message loop. In this case it shows 100% load even if the real CPU usage is 0%, so don't trust it much. Did you actually notice an increased load - slow working, increased response time, delayed window open/close? You should if there was indeed 100% load.

Did the performance problem go away when the program was uninstalled, or did you not test this?
